Abstract

Diffusion Weighted Imaging (DWI) is a sequence used in brain tumor cases to assess molecular movement (diffusion). DWI is influenced by the selection of the b-value parameter which results in differences in the generated signal. The aim of this study is to determine the differences in b-value variations of 500, 1000, 1500 s/mm2 in brain tumor cases and identify the most optimal variation. This study is a pre-experimental study conducted using a 1.5 Tesla Philips MRI machine at a private hospital in South Jakarta from March to April 2023. The sample consisted of twelve DWI MRI images with different b-value variations. Visual grading analysis was performed by three radiology specialists, and the data were analyzed using the Friedman test in SPSS. The results showed a significant difference in image information based on the use of different b-value variations, with a pvalue of 0.05 (2.36). The use of a b-value of 1000 s/mm had the highest mean rank in the basal ganglia, cerebellum, thalamus, pons, gray matter, and lesions. The difference in image information with b-value variations visualized different brain tumor representations due to increased noise with higher b-values and suboptimal image sharpness with lower b-values due to low signal intensity. The use of b-value variations of 500, 1000, 1500 s/mm2resulted in differences in anatomical image information in sequences DWI MRI brain axial of brain cases tumor due to differences in image noise and signal intensity, with a b-value of 1000 s/mm being the most optimal variation.

Abstract

This study aims to describe the procedures for managing MRCP examinations in cases of cholelithiasis at Husada Hospital, Jakarta. This type of research is descriptive qualitative using questionnaire sheets which are used for direct observation, documentation, interviews and literature studies, then data reduction is carried out, categorized and interpreted. Observations were carried out in May- July 2023 with the subjects of this study using 2 patients. From the results of the study it can be described that the MRCP examination technique with cholelithiasis cases at Husada Hospital Jakarta has a special preparation procedure, namely fasting for 5-6 hours and 30 minutes before the examination the patient drinks bittertea (2 sachets of tea bags/4.6 g mixed with mineral water 100 ml) added with 2 mlgadolinium contrast. Patients must first screen to ensure that there are no ferromagnetic materials, this examination uses a sequence that includes a 3-plane localizer, axial dual echo, axial T2, coronal T2, thick slab, 3D MRCP Respiratory Trigger or 3D MRCP Breath hold with time 40 minute check. MRCP examination produces Axial, Coronal and 3D sections in preparation for the patient drinking bitter tea and gadolinium with the addition of 3D MRCP RTR or 3D MRCP BH sequences which can optimally show the anatomy, physiology and abnormalities ofthe gallbladder and biliary system.
